Gravity type water purifying device

Abstract

The invention relates to a gravity type water purifying device, and relates to the technical field of water purifying treatment. Since the water purifying capacity of an existing water purifying device cannot be adjusted, purified water is more likely to be mixed with a large number of particles. According to the scheme, the gravity type water purifying device sequentially comprises a flocculationarea, a water purification settling area and a fine filtering area in the water flow direction. The water flow direction of the water purification settling area is from bottom to top, and the water purification settling area is internally fixedly provided with a plurality of water purification channels distributed in arrays. The water purification channels are obliquely arranged. The water purification settling area is internally provided with two parallel connecting frames. A plurality of adjusting pieces are fixedly connected between the two connecting frames. Each adjusting piece corresponds to one water purification channel, penetrates through the corresponding water purification channel and is attached to the inner wall of the water purification channel. A driving assembly is installed in the water purification settling area. The driving assembly can make the adjusting pieces attached to the inner walls of the water purification channels or away from the inner walls of the waterpurification channels, and therefore the hydraulic radius of the water purification channels is changed, and the water purification capacity is changed.

Description

technical field [0001] The invention relates to the technical field of water purification treatment, in particular to a gravity type water purification device. Background technique [0002] At present, in water treatment projects, in order to remove suspended solids and reduce turbidity in raw water, the water purification process of coagulation sedimentation filtration is usually used. The three basic processing units of flocculation, sedimentation and filtration are organically combined into one, collectively referred to as an integrated water purifier. [0003] For example, the integrated water purifier whose application publication number is CN102153178A includes a flocculation reaction zone, an inclined tube sedimentation area, a sludge concentration area, and a backwashing area, and an inclined tube is arranged in the inclined tube sedimentation area. The sewage to be purified is flocculated in the flocculation reaction zone, and is precipitated and separated in the i...

AI Technical Summary

Problems solved by technology

[0004] However, there are deficiencies in the above-mentioned water purification methods. Since the inclined tubes or inclined plates in the inclined tube sedimentation area are fixed in the purification tank, the water purification capacity of the water purification device is fixed. , the particulate matter content in the sewage discharged into the purification tank is relatively high, and the above-mentioned water purification devices often cannot achieve water purification well, which leads to a lot of particulate matter mixed in the discharged "clean water"
